AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

The installation of TU250 comparator/ 

selector (CS) boards, however, has resulted in 

a few occurrences of erratic engine 

behaviour, in the form of unexpected N1 

variations and/or illumination of the ‘‘GOV’’ 

warning light. The conclusions from an 

investigation by Turbome ́ca are that these 

malfunctions are due to a lapse of quality 

control in the varnishing process applied to 

the boards, and that only boards in a specific 

serial number range, as defined under 

‘‘Applicability’’ and referred to below as the 

‘‘suspect batch’’, are affected. 

We are issuing this AD to prevent loss 

of automatic engine control during flight 

due to an uncommanded engine rollback, which could result in the inability 

to continue safe flight. 

DATES: This AD becomes effective July 

13, 2010. The Director of the Federal 

Register approved the incorporation by 

reference of certain publications listed 

in this AD as of July 13, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on March 31, 2010 (75 FR 

16022). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states that: 

The installation of TU250 CS boards, 

however, has resulted in a few occurrences 

of erratic engine behaviour, in the form of 

unexpected N1 variations and/or 

illumination of the ‘‘GOV’’ warning light. The 

conclusions from an investigation by 

Turbomeca are that these malfunctions are 

due to a lapse of quality control in the 

varnishing process applied to the boards, and 

that only boards in a specific serial number 

range, as defined under ‘‘Applicability’’ and 

referred to below as the ‘‘suspect batch’’, are 

affected. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

10 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with this 

AD. The average labor rate is $85 per 

work-hour. Required parts will cost 

about $3,500 per product. Based on 

these figures, we estimate the cost of the 

AD on U.S. operators to be $35,850. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this AD: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 


srobinson on DSKHWCL6B1PROD with RULES
Federal Register / Vol. 75, No. 109 / Tuesday, June 8, 2010 / Rules and Regulations 32261 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone 

(800) 647–5527) is provided in the

unexpected N1 variations and/or 

illumination of the ‘‘GOV’’ warning light. The 

conclusions from an investigation by 

Turbome ́ca are that these malfunctions are 

due to a lapse of quality control in the 

varnishing process applied to the boards, and 

that only boards in a specific serial number 

range, as defined under ‘‘Applicability’’ and 

referred to below as the ‘‘suspect batch’’, are 

affected. 

(2) We are issuing this AD to prevent loss 

of automatic engine control during flight due 

to an uncommanded engine roll-back, which 

could result in the inability to continue safe 

flight. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

(1) Within 50 operating hours from the 

effective date of this AD, replace any CS 

board, P/N 0 177 99 716 0, with a S/N from 

241EL to 1192EL (inclusive), that has fewer

replace the boards. 

(2) During the next 500-hour inspection, 

replace any CS board, P/N 0 177 99 716 0, 

with a S/N from 241EL to 1192EL (inclusive), 

that has 200 HSN or more. Use paragraph 2 

of Turbomeca S.A. MSB No. 298 73 0810 

Version B, dated April 27, 2009, to replace 

the boards. 

FAA AD Differences

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

CFM International, S.A. models 

CFM56–3 and –3B turbofan engines. 

This AD requires initial and repetitive 

inspections for damage to the fan 

blades. This AD results from a report of 

a failed fan blade with severe out-oflimit wear on the underside of the blade 

platform where it contacts the damper. 

We are issuing this AD to prevent 

failure of multiple fan blades, which 

could result in an uncontained failure of 

the engine and damage to the airplane. 

DATES: This AD becomes effective July 

13, 2010. The Director of the Federal 

Register approved the incorporation by 

reference of certain publications listed 

in the regulations as of July 13, 2010. 

ADDRESSES: You can get the service

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to certain CFM International, 

S.A. models CFM56–3 and –3B turbofan 

engines. We published the proposed AD 

in the Federal Register on July 23, 2009 

(74 FR 36420), and published a 

supplemental proposed AD in the 

Federal Register on April 1, 2010 (75 

16361). Those actions proposed to 

require initial and repetitive inspections 

for damage to the fan blades. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We previously 

responded to the comments received on 

the original proposed AD in the 

supplemental proposed AD. We have 

considered the one comment received 

on the supplemental proposed AD. The 

commenter supports the proposal. 

Conclusion 

We have carefully reviewed the 

available data, including the comment 

received, and determined that air safety 

and the public interest require adopting 

the AD as proposed. 

Costs of Compliance 

We estimate that this AD will affect 

50 engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 8 work-hours per engine to 

perform the AD actions, and that the 

average labor rate is $80 per work-hour. 

Required parts will cost about $38,000 

per engine. Based on these figures, we 

estimate the total cost of the AD to U.S. 

operators to be $1,932,000.

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of
